How to Remove Stain in Quartz Countertop

Quartz countertops are popular in modern kitchens and bathrooms due to their durability, stylish appearance, and low maintenance. However, like any surface, quartz can get stained from spills and daily wear and tear. Don’t panic if you get a stain on your quartz countertop – these types of stains can usually be removed with a little bit of effort. Here is a comprehensive guide on how to remove stains from quartz countertops.

What Causes Stains on Quartz Countertops?

Quartz is non-porous, so spills and stains remain on the surface rather than absorbing into the material. Common causes of stains include:

  • Food and beverages – Coffee, tea, wine, juice, and cooking oils can leave behind colored stains.
  • Chemicals and cleaners – Products like bleach, oven cleaners, and drain cleaners can etch or discolor quartz.
  • Metal marks – Pans, pots, and metal utensils may scratch quartz and leave gray marks.
  • Hard water spots – Mineral deposits from tap water can leave white stains.
  • Dyes and pigments – Hair dye, makeup, ink, and paint can stain if left on the surface.

How to Remove Stains from Quartz Countertops

Step 1: Try a Gentle Cleaning Solution

For most stains, start by trying a gentle cleaning solution specifically designed for stone surfaces. Look for products labeled “stone cleaner” or “granite cleaner” that contain ingredients like hydrogen peroxide, isopropyl alcohol, or ammonia. Avoid bleach and acidic cleaners which can damage the quartz surface.

Mix the stone cleaner with warm water per the product instructions and apply it to the stain with a soft cloth or sponge. Let it sit for 5-10 minutes before wiping clean with a damp cloth. This should lift many fresh stains.

Step 2: Use Baking Soda or Hydrogen Peroxide

For more stubborn stains, make a paste with baking soda and water and gently rub it into the stained area using a soft cloth or sponge. You can also try spraying hydrogen peroxide directly on the stain. Let both solutions sit for 10 minutes before rinsing clean. The abrasiveness of baking soda combined with the oxidizing effect of hydrogen peroxide often helps lift set-in stains.

Step 3: Try a Poultice

For really stubborn stains that resist baking soda and hydrogen peroxide, you can make a poultice. This draws out deep set stains from within the stone.

To make a poultice:

  • Mix a cleaning powder like baking soda, barkeeper’s friend, or Bon Ami with just enough hydrogen peroxide to make a spreadable paste.
  • Apply a 1/4 inch thick layer of the paste to the stain and cover it with plastic wrap.
  • Leave it for 24-48 hours, reapplying if it dries out.
  • Remove the plastic and rinse away the poultice. Scrub any remaining stain residues.

Step 4: Use a Polishing Powder

For stains that leave a dull etched spot, use a polishing powder specifically formulated for quartz and stone countertops. Powders containing aluminum oxide gently buff out etching and restore the quartz to its original shine.

Rub a damp cloth soaked in the polishing powder over the stained area using circular motions. Rinse thoroughly and buff dry with a soft towel. Avoid polishing the entire countertop surface which will make it appear uneven.

Step 5: Call a Professional

If you have tried all of these methods and the stain still remains, contact a professional stone restoration company. They have access to more powerful cleaning solutions and tools that can remove the most stubborn stains without harming quartz. This may be your best option for old set-in stains.

Tips to Prevent Stains on Quartz Countertops

Preventing stains in the first place will save you the hassle of having to remove them. Here are some handy tips:

  • Use cutting boards and trivets to protect the surface from kitchen knives, hot pans, and appliance heat.
  • Clean up spills immediately before they have a chance to set in.
  • Seal quartz regularly with a stone sealer to create a protective barrier.
  • Avoid exposing quartz counters to strong chemicals like paint removers, oven cleaners, etc.
  • Use coasters under glasses and don’t place wet items directly on the counter.
  • For heavy cleaning tasks, use a less harsh stone cleaner instead of abrasive scrubbers.

Frequently Asked Questions

How do I know if my countertop is quartz?

Quartz countertops are non-porous, very hard and scratch-resistant. They are usually smooth with a uniform appearance, unlike natural stone that has more variation. Quartz also does not require regular sealing like granite or marble.

Can all stains be removed from quartz?

Most stains can be removed from quartz surfaces if treated promptly. However, etching from chemicals or discoloration from extreme heat may permanently damage the finish. Avoid exposing quartz counters to these conditions.

What household items can I use to clean quartz?

You can clean quartz with mild dish soap and water for daily maintenance. For tougher stains, use a stone cleaner, hydrogen peroxide, baking soda, or polishing powder formulated for quartz and other engineered stones. Avoid abrasive cleansers.

How can I restore the shine to a stained quartz countertop?

Use a polishing powder made specifically for quartz to gently buff out dull, etched areas. Focus just on the stained spot, not the whole counter. You can also try a quartz surface polish or sealer to renew the overall luster.

Will a bleach cleaner remove stains from my quartz counter?

No, avoid using bleach or acidic cleaners on quartz. The chemicals can damage, etch or discolor the surface. Opt for a mild stone cleaner instead for the safest cleaning results.


While quartz countertops are pretty stain-resistant, they can become marked over time with daily use. But don’t despair if you get a stubborn stain – just try the effective techniques outlined above to safely remove it without harming the quartz surface. With the proper care and cleaning methods, you can keep your quartz counters looking like new for years. Just be sure to wipe up spills quickly and use trivets and cutting boards to minimize the chance of stains occurring in the first place.
